DESIGN AND PRODUCTION OF A MILLIREACTOR SYSTEM WITH A pH-SENSITIVE COATING
The aim of this work was to design a millireactor system and to coat the surface of the channel with a pH-responsive sensor film. The sol-gel method was used to prepare the sensor film. The main objective was to obtain a functional pH sensor film that shows a clear response in real time within the channels of the millireactor. For the sol-gel method, tetraethoxysilane (TEOS) and phenyltrimethoxysilane (FTMS) were used as precursors with ethanol as solvent, the reaction was acid catalyzed using hydrochloric acid and methyl red was used as pH indicator. The obtained sensor films were first tested on plates and then applied in millireactor channels. Both the test plates and the millireactors were fabricated using stereolithography (SLA) 3D- printing technology. Tests on the plates showed that excessive thickness of the film leads to cracking, which causes leaching of the indicator and detachment of the film from the surface. Therefore, different methods were used to obtain thinner films. The results show a change in the color of the sensor films with the change in the pH of the solution inside the channels of the millireactor (Fig. 1). The time interval of the change was 5 minutes.
